Deprecated notice for preg_match

My PHP version is 8.1.23?and I am seeing a deprecated notice. I have adapted this code and it got resolved but please fix it in the next update:

	/**
	 * Check if key is valid
	 *
	 * @param $key
	 *
	 * @return bool
	 */
	public static function keyIsValid( $key ) {
		return is_string( $key ) && ! preg_match( '/[^\p{L}\p{N}\:\.\_\s\-]+/u', $key );
	}
